使用 Azure Cli 或 Azure REST 禁用 AFD 后端池的后端主机 API

Question

我正在尝试更新 AFD 后端池的现有后端主机，使其状态从 Enabled 变为 Disabled。

有没有办法更新 Front Door 后端池的现有后端主机？

目前，我只能在以下 azure front door cli docs:

中看到 add、list 和 remove

az network front-door backend-pool backend add
az network front-door backend-pool backend list
az network front-door backend-pool backend remove

有 update 吗？

我也查看了 Azure REST API docs，但没有找到端点来更新 AFD 后端池的后端主机。

Answer 1

我可以使用 PowerShell 实现您的要求。

这是脚本：

$resourceGroup1 = "frontdoor" $frontDoor1 = "msrini"

$afd = Get-AzFrontDoor -ResourceGroupName $resourceGroup1 -name $frontDoor1

$loadBalancingSetting1=$afd.LoadBalancingSettings

$afd.BackendPools.backends[0].EnabledState = "Disabled"

$backendpool1=$afd.BackendPools

$frontendEndpoint1 = $afd.FrontendEndpoints

$healthProbeSetting1= $afd.HealthProbeSettings

$routingrule1 = $afd.RoutingRules

$backendpoolsettings1 = $afd.BackendPools设置

设置-AzFrontDoor -名称$frontDoor1 -ResourceGroupName $resourceGroup1 -RoutingRule $routingrule1 -BackendPool $backendpool1 -FrontendEndpoint $frontendEndpoint1 -LoadBalancingSetting $loadBalancingSetting1 -HealthProbeSetting $healthProbeSetting1 -BackendPoolsSetting $backendpoolsettings1

我能够解决我的问题，下面的脚本需要使用具有登录服务原则的 azure cli。

Param(
  [string]$desiredState, #"Enabled" or "Disabled"
  [string]$frontDoorName,
  [string]$resourceGroupName,
  [string]$targetBackendPool,
  [string]$targetBackendHost
)

# Get Access Token
$token = az account get-access-token | ConvertFrom-Json
$accessToken = $token.accessToken
$subscriptionId = $token.subscription
$tenantId = $token.tenant

$uri = "https://management.azure.com/subscriptions/$($subscriptionId)/resourceGroups/$($resourceGroupName)/providers/Microsoft.Network/frontDoors/$($frontDoorName)?api-version=2019-05-01"
$headers = @{ "Authorization" = "Bearer $accessToken" }
$contentType = "application/json"

# Get AFD Configuration.
Write-Host "Invoking Azure REST API to get AFD configuration"
$afdConfig = Invoke-WebRequest -method get -uri $uri -headers $headers | ConvertFrom-Json

# Edit AFD Configuration to toggle backend host state
Write-Host "Checking BackendHost: $targetBackendHost In Backend Pool: $targetBackendPool"

foreach ($backendPool in $afdConfig.properties.backendPools) {
    if ($backendPool.name -eq $targetBackendPool) {
        foreach ($backends in $backendPool.properties.backends) {
            if ($backends.address -eq $targetBackendHost) {
                $currentState = $backends.enabledState
                Write-Host "Current State of $targetBackendHost is $currentState"
                if ($currentState -eq $desiredState) {
                    Write-Host "$targetBackendHost is already in the desired state of $desiredState"
                    exit
                }
                $backends.enabledState = $desiredState
                Write-Host "$targetBackendHost Updated to $desiredState."
           }
        }
    }
}

$updateRequest = $afdConfig | ConvertTo-Json -Depth 100

# Update AFD Configuration.
Write-Host "Invoking Azure REST API to update AFD configuration"
Invoke-WebRequest -method put -uri $uri -headers $headers -ContentType $contentType -body $updateRequest

# Poll current state until the change has been fully propogated in azure
Write-Host "Polling AFD until update is complete."
do {
    $afdConfig = Invoke-WebRequest -method get -uri $uri -headers $headers | ConvertFrom-Json

    foreach ($backendPool in $afdConfig.properties.backendPools) {
        if ($backendPool.name -eq $targetBackendPool) {
            foreach ($backends in $backendPool.properties.backends) {
                if ($backends.address -eq $targetBackendHost) {
                    $currentState = $backends.enabledState
                }
            }
        }
    }
    Write-Host "$targetBackendHost is currently in $currentState"
    Start-Sleep -Seconds 1
} until ($currentState -eq $desiredState)

Write-Host "$targetBackendHost has successfully been updated to $desiredState"

Answer 3

我是用 Powershell 做的

$FrontDoor = Get-AzFrontDoor -ResourceGroupName "FrontDoorResourceGroupName" -Name "FrontDoorName"
$FrontDoor.BackendPools.Backends[0].EnabledState = "Disabled"
Set-AzFrontDoor -InputObject $FrontDoor
